Infrastructure you can rely on
Resilient and always available

Our data centres are built and operated to provide you with a resilient and always-available hosting environment.


We understand that outsourcing mission-critical IT systems involves trust. This governs the principles on which we design and maintain our data centres. As such they are built to the highest industry standards, offer high levels of physical and environmental resilience and are protected against fire and power outage.

All our data centres use computerised Building Management Systems (BMS) that monitor and remotely operate sensors covering electrical, mechanical, fire detection and leak detection systems.

Redundant power

To ensure continuous operation, our data centres have access to redundant high-capacity power supplies, scalable for future expansion. Every site provides Uninterruptible Power Supply (UPS) systems and standby diesel generators capable of supporting the site indefinitely in the unlikely event of a failure of grid-power.

Energy efficient

We take cooling very seriously in our data centres and use a combination of water-based, fully-redundant air conditioning. In addition we use hot aisles/cold aisle designs, or innovate containment solutions for the best cooling.  Energy efficiency has been at the forefront of the design and build of our data centres. Many of our data centres benefit from free cooling systems which enable significant savings when the external ambient temperatures fall below a certain level.

Intelligent fire protection

Very Early Smoke Detection Apparatus (VESDA) or alternative sophisticated detection technology is installed in every facility. These highly sensitive two-stage smoke detectors are linked to the BMS and monitored continually from a network operations centre. In the unlikely event of a fire, we have environmentally-friendly gas-based or water mist fire suppression systems that quickly extinguish any fire. Systems are designed to minimise any disruption and ensure that any minor problem remains localised.
